I AUTOMATIC SPRINKLER.

Application filed May 27, 1914.. Serial No. 841,287.

- To all whom it may concern:

' gether, when the valve is seated against the sprinkler head for use in fire extinguishing I apparatus. r

The present invention contemplates'the' provision of a sprinkler head including a discharge nozzle, a combination valve and deflector or spreader, and'a unique means for normally maintainingthe valve seated.

upon the nozzle to close the same, and for enabling the valve and deflector to be thrown open, under the pressure of the a water or fire extinguishing agent, when the said means is released, in order that :the

spreader or deflector will serve to spread the water over a comparatively large area.

Another objectof the .present invention ,is to provide a device of the natureindicat'ed, which may be compactly folded tonozzle, to hold the valve seated,and to enable the valve holding means to be held in place by means of suitable fusible material,

the structure being comparatively simple, compact and inexpensive in construction, as well as being simple, practical and eiiicient in operations,

With the foregoing andother objects in view which will appear as the descriptionproceeds, the invention resides in the combination and arrangement of parts and in-the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention'herein disclosed can be made within the scope of what .is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, w \erein.

lar or hollow. The lower end. portion of the body 1 is formed into a nipple '2 to engage downwardly within the top of the sprinkling pipe, as is'usual in devices of this character. The body lifurther includes an upstanding nozzle portion 3, the-upper endgof which forms avalve seat. The body end of the nozzle 3.

A pin or rivet .16 is engaged through the arms or branches of .the bifurcated portion 14;, and is engageable with the link 6 to serve as a stop, as seen in Fig. 3, when the link and valve 11 have swung upwardly to A open position.

In order to assist in the unseating'or opening of the valye 11, a coiled wire spring 18 Figure l s a sectional view of the spr1n- As a means for swinging the valve 11, I

away from the link 6, the link is provided at that side adjacent the valve, with a rece s .19, in which a flat spring 20 is secured, the

spring 20 having a flexible or resilient leaf 21 cooperable with the valve 11. Thus, when the valve 11 is swung against the link 6, the leaf 21 is arranged to be swung back into the recess 19 by the valve, and when the valve is released, the spring leaf 21 will spring away from the link 6, "to thereby throw or force the valve 11 away from the link.

The parts are so arranged, that when the valve 11 is swung against the inner side of the link 8, the spring leaf 21 being swung within the-recess 19, and when the link is swung downwardly so that its tongue 9 engages the slot or kerf 10 of the arm 5, the valve 11 will be seated tightly upon the nozzle 3, the link 6 and its spring20 bearing upon the upper or outer surface of the valve 11, or the deflector or spreader 18 of the valve, to hold the valve seated. The valve being seated will compress the spring 18. The parts are held in this closed position, by means of solder or other fusible material 22 which binds or secures the free end of the link 6 to the arm 5, under ordinary conditions, Thus, the solder or fusible material 22 will resist the upward movement of the ,"link 6, under the water pressure against the valve 11, under ordinary conditions, but

should the solder or fusible material 22 be come heated to an abnormal degree, such as is caused by conliagration, the solder or material 22 being fused, will release the link 6 so that the link 6 may be thrown upwardly by reason of the water tossing the valve 11 upwardly. The spring 18 also assists in unseating the valve, should the valve stick. Thus, when the .valve 11 is opened, due to the releasing of the link 6, the link 6 will be swung to erect position, andthe valve 11 will be thrown from the link by the.

7 spring 20 and will be reversed or turned upside down, with the pin or stop 16 engaging the link 6, to prevent the excessive upward movement ofthe valve 11 and the deflector or spreader 13 carried thereby. In this manner, the spreader or deflector 13 will be brought into operation, and will lie directly in the path of the stream of water issuing from the nozzle 3, so that the water will be spread or deflected radially in all directions to extinguish the adjoining cdni'lagration.

The present device may be readily reset,

to close the passage through the body and .nozzle, as seen in Fig. l, and as will be ob vious without further description.

The present device may be, and preferably is, operated in an upright position, but may be operated in other positions as well. il hen the parts are folded, as seen in 1, to close the! valve, the parts will be more or less, and the tendency or breakage of the parts, will be minimum. The snrink simple construct -1, 1t
